ALARM ILLUMINATOR CLOCK Filed March 11, 1929 vwantoz flbtm 3g)? ald/MW Patented June 2, 1931 NETED STATES EDWIN FLOHR, OF BROOKLYN, NEW YORK ALARM ILLUMINATOR CLOCK Application filed March 11, 1929. Serial No. 345,923.

The main object of this invention is to provide a clock which will awaken a sleeper by means of a filament lamp through which an electrical circuit is closed the instant that 6, the alarm begins to ring.

Another object of this invention is to provide a clock having in combination therewith a filament lamp which is illuminated at the instant that the alarm mechanism of the clock is actuated.

I The above and other objects will become apparent in the description below, in which characters of reference refer to like-named parts in the drawings.

Referring briefly to the drawings, Figure 1 is a rear elevational View of the device, showing the filament lamp, the clock mechanism, and the means for closing the contact of said filament lamp.

Figure 2 is a side elevational view of Figure 1 with aportion of the cabinet cut away to illustrate the filament lamp contact closing means.

Figure 3 is a side elevational view of the mechanism operating the filament lamp contact closing mechanism.

Referring in detail to the drawings, the numeral 10 indicates the body plate of a clock mechanism. This body plate is secured to a dial face 11 which latter is spaced-apart from the body plate 10, and bet-ween these two members 10 and 11 the mechanism of the usual type of clock is located. This entire clock mechanism is securely housed within a cabinet comprising side walls 12 and 13, a front wall 14, a top 15, and av bottom 16, and this cabinet may be closed at the rear by a cover not shown on the drawings. The desirable clock mechanism for this device is preferably equipped with an alarm mechanism. This alarm mechanism essentially consists of a spirally wound spring 17 which is mounted upon a shaft 18. hen the bell 19 of the alarm mechanism tolls, the spiral spring 17, which actuates the alarm mechanism, is unwound, carrying rotationally with it the shaft 18. Mounted upon this shaft 18, on the one side of the body plate 10, is a collar 20 which is provided with a cammed surface 21. This cammed surface or face 21 consists of an inclined surface with a shoulder or step 22 therein, the step 22 facing in a clockwise direction. The collar 20 is rigidly secured to me shaft 18 by a pin 23. A sleeve 24 is loosely mounted on the shaft 18 and its one face is provided with a cam structure complemental to the cam surface 21 on the collar 20. This sleeve 24 is urged into cooperating position with the collar 20 by a coil spring 25 which latter seats upon a flange 26. The purpose of the construction heretofore described regarding the collar 20 and sleeve 2i will be more fully hereinafter described. he sleeve 24 is provided with a follower arm 27. Above the follower arm 27 a reciprocating spindle 28 is mounted. This spindle 28 is slidably positioned in openings formed in he walls 12 and 13, and the spindle 28 is equipped on its bottom side with a tongue 29 which is adapted to be engaged by the follower arm 27 on the sleeve Mounted above the spindle 28 is a yoke 30 whose arms 31 and 32 rise in an upright position. These arms 31 and 32 of the yoke 30 are adapted to lie in contact with the button members 33 and 3 of an electric light socket fixture 35 which is adapted to receive a filament lamp The leads 37 leading to this socket fixture 35 are adapted to be connected to the plug socket of a source of electrical energy. The socket fixture 35 is of the common and well-known construction, in which oppositely operable buttons 33 and 34 are utilized.

In use, the device is adapted to illuminate the filament lamp 36 by closing the contacts in the socket fixture 35 when the alarm mechanism of the clock situated within the cabinet is actuated. The clock mechanism is of the usual alarm construction and is adapted to set the alarm mechanism in action at a predetermined instant. As the alarm mechanism. is actuated, the shaft 18 rotates with the spiral spring 17 This shaft 18, having the collar 20 secured thereto by the pin 23, causes said collar 20 to rotate therewith. The sleeve 24, mounted loosely on the shaft 18, is caused to be continually interlocked with the cam surfaces 21 on the collar 20 and with the spring 25 and thus will also be 'caused to rotate with the shaft 18 when the shaft 18 rotates in a clockwise direction.

Previous to the time that the alarm mechanism is to be operated, the protruding end of the spindle 28 is urged into the cabinet so that the tongue 29 comes into close proximity with the follower arm 27. The latter, forming part and extending radially from the sleeve 24, rot-ates with the sleeve 24 and in coming into contact with the curved tongue 29 urges this tongue 29 to one side. In so doing, it carries with it the spindle 28 and the arms 32 and 31 of the yoke 30. This movement is toward one side of the cabinet and the button 34 will be depressed or urged into the mechanism of the socket fixture 35, thereby closing the circuit through this socket fixture 35 and illuminating the filament lamp 36 at the same instant that the alarm is actuated. To prevent any damage ensuing tothe mechanism it is desired that the sleeveQd, having thereon the follower arm 27, be loosely mounted in place on the shaft 18 in order that when the spiral spring 17 is to be wound or tautened, or in the event that the tongue 29 lies in contact with the follower arm 27, the sleeve 24 r will not be rotated when the shaft 18 is rotated in a clockwise direction in which the spiral spring 17 i-swound or tautened. By loosely mounting the sleeve 2 on the shaft 18 and providing the sleeve 2 1 and the collar 20 with interlocking camsurfaces, the structure aflords an escapement ornon-rotation of the sleeve in one direction, and in the opposite direct-ion the collar20 positively carries the sleeve 24 with the shaft 18 when the'latter is being rotated.

It is to be noted that certain changes in form and construction may be made without I operating with said spindle to shift the latter,

and means for locking said sleeve to said shaft when said shaft is rotated in a clockwise di- .rect1on.

2, In a device of the class described, a cabinet, an alarm clock mechanlsm mounted in said cabinet, a push button operated socket in said cabinet, an alarm mechanism shaft, a spindle reciprocal in said cabinet, said spindle having both ends protruding from "said cabinet, saidspindle engaging said push buttons, a tongue on said spindle, a sleeve looselymounted on said shaft, a followerarm 'to rotate said sleeve on said shaft when said shaft is rotated. 3. In a device of the class described, a
